I know Apple has a habit of under rating the performance of its products especially for water resistance on the products, but when Apple unveiled the AW Series 2, they said the battery life was unchanged and still around 18 hours. My original Apple Watch I charged nightly and sometimes could go a day and a half off a charge but not often, but my new Series 2, I can go 2 full days without charging and have done so a few times even when using a sleep tracking app all night, I still wake up at over 60% after wearing it the day before.

I suspect that when Apple stated their 18 hour battery life figure they assumed that there would be some gps use during those 18 hours and the gps is a pretty big power user. If you're not using the gps then it doesn't surprise me that you're able to exceed their estimation.

I know when setting up the watch I allowed GPS use, but I guess then it would only activate if using the exercise feature maybe?

You have the 42mm I guess. The 38mm doesn't last 2 days. I have to put my 38mm on charge every night when it's about 45 percent. Otherwise it's too low in the morning.

Yup, I have the 42mm. I know the 38mm has a smaller battery, but my Gen 1 AW was a 42mm and I never came close to this battery life, thats why it surprised me so much.

I charged my Series 2 last on Wednesday about 1700h GMT. I've still got about 20% left. I'm very impressed with the battery life. Way exceeds my expectations.

I'm blown away at the Apple watch series 2 42mm got up at 4am put watch on at 4:30am. Currently 12:30 am and I have 65%.

I actually went to sleep at 4:30am and I had 63% left on the Apple watch. Amazing battery compared to series 0.

I have the S2 and love my battery, off charge 15 hours a day and usually a 40 min GPS run and I'm still in the 60 some percent range at bed time. I could easily get 2 days out of it but just don't want to sleep with a watch on.

my series 2 battery life is stunning.

even with 1 hour of pure workouts it hardly dropped at all. lasted me a good two days.

Apple creates what they think is a typical usage pattern and from there measures and rates the battery performance. That usage pattern may be close to your actual usage or may not. For me, I doubt it will be close to what I would actually use it for, i.e., running for an hour, later an hour cardio class and then a karate class. I don't say this as way to sound pompous or arrogant, but rather my work out schedule typically can exceed what apple considers normal.

To much hard work for me, my usage pattern is more like getting a reminder when I should stand up and get out of my chair or scan my airport tickets and pay for the public transport in London :)

Oh and about 10 miles of dog runs per day :)

Mine lasts between 2-3 days at the moment realistically.

I kept a log the first week of my AW series 2, 42mm. With normal use the watch can go for 2 days easily (3 if you want it to shut off at some point during that 3rd day). I was charging it every night to reset it to 100% during the time I was keeping a log. Here's what I got:

Battery log

Day 1 (9/30/16) : 55%

Day 2 : 77% weekend stayed around house and tasks/chores

Day 3 : 77% weekend house and tasks

Day 4 : 72% used 730am-1006pm, workday

Day 5: 63% 730am-1150pm workday and walk w/gps

Day 6: 53% 730am-1116pm workday + 1 workout run w/ gps

Day 7: 76% 830am-1133pm workday

Mine is not nearly as good.
I have a 42mm Series 2 (SS Black).

I don't use it a lot or workout every day and it is usually at about a 26-30 hour pace. It will use about 33% every 8-10 hours. That's fine, but it's not nearly what everyone is reporting.

My Series 1 is at 88% after 10 hours but I'm still going to upgrade to Series 2, mostly for battery life as I will hardly use any of the other features.
